[one-users] annoying IP allocation

[François Thiebolt]

Hi Simon,

Thanks for the tip:

onevnet hold production 172.28.112.255
onevnet hold production 172.28.113.0

oneadmin at cloudmip[onevnet] onevnet show 0
VIRTUAL NETWORK 0 INFORMATION
ID             : 0
NAME           : production
USER           : admin
GROUP          : oneadmin
CLUSTER        : -
TYPE           : RANGED
BRIDGE         : br0
VLAN           : No
USED LEASES    : 2

PERMISSIONS
OWNER          : um-
GROUP          : u--
OTHER          : u--

VIRTUAL NETWORK TEMPLATE
BRIDGE="br0"
IP_END="172.28.113.240"
IP_START="172.28.112.101"
NAME="production"
NETWORK_ADDRESS="172.28.112.0/23"
TYPE="RANGED"

RANGE
IP_START       : 172.28.112.101
IP_END         : 172.28.113.240

LEASES ON HOLD
LEASE=[ MAC="02:00:ac:1c:70:ff", IP="172.28.112.255", IP6_LINK="fe80::400:acff:fe1c:70ff", USED="1", VID="-1" ]
LEASE=[ MAC="02:00:ac:1c:71:00", IP="172.28.113.0", IP6_LINK="fe80::400:acff:fe1c:7100", USED="1", VID="-1" ]

VIRTUAL MACHINES

    ID USER     GROUP    NAME            STAT UCPU    UMEM HOST             TIME


this solved my issue :)
(to OpenNebula team: anyway, allocating IP addesses of either the network or the broadcast address is definitively not a good idea.)

Thanks
François
